The answer is the option (c) \left [ H_{2}SO_{4}\rightarrow H_{2}O+SO_{2}+O \right ]\times 2

                                                                     C+2O\rightarrow CO_{2}

                                                C+2H_{2}SO_{4}\rightarrow CO_{2}+2SO_{2}+2H_{2}O

CO_{2} and SO_{2} are two gaseous products formed by oxidation of C by H_{2}SO_{4}
